Frequently Asked Questions About Furnace Repair

QUESTION: How Can I Tell If My Furnace Needs Repaired?

There are several signs that could signal the need for a furnace repair. One of the most common indicators is delayed ignition, which is usually caused by a faulty igniter and will likely require replacement. Regularly cleaning the furnace can help prevent early igniter failure. Another common sign is persistent shrieking or grinding sounds, which are caused by moving parts with inadequate lubrication. Such issues can be prevented with regular maintenance and inspections.

QUESTION: Why Isn’t My Furnace Blowing Hot Air?

If the furnace isn’t blowing hot air, the main blower is likely to blame. Access to the blower may be limited depending on the type of furnace that you have. If you can easily access it, turn off the furnace, clean off any dirt and debris on the blower, then try turning it on again. If it still doesn’t work, your furnace may need a new blower.

QUESTION: How Often Does My Furnace Require Maintenance?

Scheduled furnace inspection and maintenance is ideally conducted once a year. We recommend sticking to a regular maintenance schedule as much as possible since putting off maintenance increases the chances of furnace failure during the months when you need it most. You should also clean and inspect your furnace, as well as clean or replace the filters, at least once every three months.

QUESTION: How Do I Know If I Need a New Furnace?

Furnaces have an expected life span of about 18 years, assuming they receive proper care and maintenance. High-efficiency furnaces may have a shorter expected lifetime, however, which can be considered a fair trade-off for their other great benefits such as energy savings. A furnace that’s a few years older than its service life can still be useful, but won’t be as efficient as it was. If your furnace is up for replacement, consider upgrading to one with higher AFUE (Annual Fuel Utilization Efficiency) rating.
